The dashboard can not be correctly started

[ryueran]

Hi, I am a starter of Ankaios framework, I deployed the dashboard in the state.yaml for Amkaios Server, but after I started ank-server and ank-agent and ank --insecure get workloads I got error like following:
WORKLOAD NAME AGENT RUNTIME EXECUTION STATE ADDITIONAL INFO
Ankaios_Dashboard agent_B podman Pending(Initial)
databroker agent_A podman Running(Ok)
I ran "podman run --rm -p 5001:5001 ghcr.io/felixmoelders/ankaios-dashboard:latest" I got error like:
File "/ankaios-dashboard/main.py", line 1, in
import DashboardAPI as api
File "/ankaios-dashboard/DashboardAPI.py", line 23, in
ank_comm_service = AnkCommunicationService()
^^^^^^^^^^^^^^^^^^^^^^^^^
File "/ankaios-dashboard/AnkCommunicationService.py", line 11, in init
self.ankaios = Ankaios()
^^^^^^^^^
File "/usr/lib/python3.11/site-packages/ankaios_sdk/ankaios.py", line 173, in init
self._connect()
File "/usr/lib/python3.11/site-packages/ankaios_sdk/ankaios.py", line 210, in _connect
raise AnkaiosConnectionException(
ankaios_sdk.exceptions.AnkaiosConnectionException: Control interface input fifo does not exist.
I check the source code of sdk in ankaios.py and I found the error was triggered by:
if not os.path.exists(
f"{self.ANKAIOS_CONTROL_INTERFACE_BASE_PATH}/output"):
raise AnkaiosConnectionException(
"Control interface output fifo does not exist."
)
And the ANKAIOS_CONTROL_INTERFACE_BASE_PATH is "/run/ankaios/control_interface", the thing is after I ran "sudo systemctl start ank-server" I did not find "/run/ankaios/control_interface" in my system, may I ask what is the cause of this issue?

Hi, thank you for reporting the issue. I somehow got the problem in the past too, when i forgot to allow controlinterface access in the state.yaml.

Try adding from (https://github.com/FelixMoelders/ankaios-dashboard?tab=readme-ov-file#how-to-use-the-dashboard-out-of-the-box):

´´´yaml
apiVersion: v0.1
workloads:
Ankaios_Dashboard:
....
controlInterfaceAccess:
allowRules:
- type: StateRule
operation: ReadWrite
filterMask:
- "desiredState"
- "workloadStates"
´´´
which version of ankaios and which version of the ankaios-dashboard do you use?

@FelixMoelders Hallo, thank you very much for your reply! I used the same yaml file as you posted in your answer, I think it was the latest version
Now I just made it run, this is how I solve this issue:

1. Just copy only the content of dashboard yaml file to the state.yaml file
2. Start Ankaois Server and start Ankaois Agent, after that I can see the dahsboard in the browser
3. Add other Agents through separate yamk files and then start them though "ank -k apply", refresh the browser, then I am able to see the new Agents in dashboard

But when I write all the Agents in state.yaml file, it did not work, maybe it is because my Ubuntu version is 22.04, about that I am not quite sure
